Answer :
C = 2πr
C = 2 * 3.14 * 5.1
C = 32.028
You can round that to A. 32.03, because if the decimal after 2 is greater than it, then you round it to the number which is higher than it, which is 3.
C = 2 * 3.14 * 5.1
C = 32.028
You can round that to A. 32.03, because if the decimal after 2 is greater than it, then you round it to the number which is higher than it, which is 3.
Answer:
Option A is correct.
Circumference of a circle = 32.03 cm
Step-by-step explanation:
Circumference of a circle(C) is given by:
[tex]C = 2 \pi r[/tex] .....[1]
where,
r is the radius of the circle.
As per the statement:
Use pi = 3.14.
Radius of the circle(r) = 5.1 cm
Substitute these given values in [1] to find C;
[tex]C = 2 \cdot 3.14 \cdot 5.1[/tex]
Simplify:
C = 32.028 cm
Therefore, the approximate value of the circumference of a circle is, 32.03 cm
